When an object floats in water, it displaces a volume of water that has a weight equal to the weight of the object. If a ship ha
swat32

The amount of seawater that will be displaced would be 1.3274 x 10^5  ft^3

<h3>Density and volume</h3>

Density = mass/volume.

Since a floating object displaces its own weight, a 4247 tons ship will also displace the same amount of water.

4247 tons of seawater = 3.8528 x 10^9 g

volume of 3.8528 x 10^9 g seawater = mass/density = 3.8528 x 10^9 g/1.025 = 3758829268.29 cubic centimeter.

3758829268.29 cm^3 = 132741.80 ft^3 or 1.3274 x 10^5  ft^3

What is the frequency of an electromagnetic wave that has a wavelength of
AlexFokin [52]

Answer:

D. 2.5 x 10 ^-14 Hz

Explanation:

Use wavelength formula: v = f x wavelength

Rearrange formula for frequency.

f = wavelength / v

f = 7.6 x 10 ^-6 / 3.00 x 10 ^8

f = 2.5 x 10^-14 Hz

Por qué los alimentos se dañan con mayor facilidad a temperatura ambiente que cuando están en la nevera?
ella [17]

Answer:

Esto se debe a que la heladera tiene mucha menor temperatura que la temperatura ambiente.

Esta menor temperatura ayuda a luchar contra los microorganismos que están en los alimentos (bacterias, hongos, etc) pues detiene en gran medida su repreduccion, la cual se ve maximizada en los rangos entre 5°C y 60°C, tal que la temperatura ambiente suele estar en el rango donde los microorganismos prosperan y se reproducen, es por ello que los alimentos se conservan mucho mejor en ambientes fríos (como la nevera) que en temperatura ambiente.
